COVER STRUCTURE OF HOUSING
Document Type and Number:
Japanese Patent JP2017171371
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To keep a click feeling in stable two states of an open state and a close state with a simple structure.SOLUTION: A box body 100 has a housing 20, and a cover body 10 coupled to the housing 20 so as to rotate about a rotary center C. On the outside in a radial direction of a shaft mechanism 11 of the cover body 10, a first engaging portion 14 and a second engaging portion 15 are formed so as to slightly project out, and on the inside of the shaft mechanism portion 11, a cavity portion 11b is formed. When the cover body 10 rotates between the open state and the close state, the cover body takes a route in which an outer peripheral surface 11a of the shaft mechanism portion 11 does not contact with either one of a first pressed portion 24 or a second pressed portion 25. The maximum value of resisting force generated to rotations of the cover body 10 when getting free from the open state or the close state, is larger than the minium value of resisting force generated to rotations of the cover body 10 in the middle of the rotation between the open state and the close state.SELECTED DRAWING: Figure 3
